This is a great revised and up to date edition of Chanin's previous Natural History Collection otter book. It is a lovely read and covers everything from some of the author's own in depth history in otter research, to otter ecology, breeding, life-cycle, habitats, and how to spot an otter to recent threats and diseases. The illustrations are beautiful. It's a lovely read, packed with information and you can dip into it anywhere and come away with all the facts. It should appeal to otter enthusiasts of all ages. Due to the lovely pictures would make a great gift!
